Each second universal joint unit 30 has a first swing axle portion 31 for the relative action unit 40 to swing forward and rearward and a second swing axle portion 35 for the relative action unit 40 to swing left and right. The first swing axle portion 31 and the second swing axle portion 35 are at the same level and perpendicular to each other. The first swing axle portion 31 of the second universal joint unit 30 is parallel to the first swing axle portion 21 of the first universal joint unit 20. The first swing portion 31 of each second universal joint unit 30 of the present invention further comprises a shaft 32 which is located at a rear section of the support member 15 and a shaft sleeve 33 fitted on the shaft 32. The shaft sleeve 33 can turn forward and rearward relative to the shaft 32. The second swing axle portion 35 has a protruding shaft 36 extending from two opposing sides of the shaft sleeve 33. The relative action unit 40 is pivotally connected to the protruding shaft 36, so that the relative action unit 40 can swing left and right relative to the protruding shaft 36.
The two action units 40 are located at two sides of the main frame 10 and connected to the respective first and second universal joint units 20, 30 at the same side. Each action unit 40 has a first lever 41 and a second lever 42 which are pivotally connected to the first universal joint unit 20 and the second universal joint unit 30, respectively. The first lever 41 has a pivot seat 411 at an upper end thereof for connecting the protruding shaft 26 and a connecting pivot portion 412 at a lower end thereof. The second lever 42 has a pivot seat 421 at an upper end thereof for connecting the protruding shaft 36 and a connecting pivot portion 422 at a lower end thereof. At least one side of each action unit 40 is provided with a connecting plate 43 which is connected to the connecting pivot portions 412, 422 of the first and second levers 41, 42. In this embodiment, there are two parallel connecting plates 43 connected to the connecting pivot portions 412, 422 of the first and second levers 41, 42. A distal end of the connecting plate 43 is pivotally connected to a middle section of a base rod 44. A front end of the base rod 44 is flush with a bottom edge of the connecting pivot portion 422 of the second lever 42. The base rod 44 can bring a footrest 45 to be folded upward. The footrest 45 is disposed on the base rod 44, and selectively connected to the base rod 44 in a fixed way or in a pivot way. Thus, the present invention provides multiple functions for exercises, with a simple configuration.
